#1368832 — [PATCH 4.2.y-ckt 006/218] gpio: add a data pointer to gpio_chip

4.2.8-ckt7 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Linus Walleij <linus.walleij@linaro.org>

commit b08ea35a3296ee25c4cb53a977b752266dafa2c2 upstream.

This adds a void * pointer to gpio_chip so that driver can
assign and retrieve some states. This is done to get rid of
container_of() calls for gpio_chips embedded inside state
containers, so we can remove the need to have the gpio_chip
or later (planned) struct gpio_device be dynamically allocated
at registration time, so that its struct device can be properly
reference counted and not bound to its parent device (e.g.
a platform_device) but instead live on after unregistration
if it is opened by e.g. a char device or sysfs.

The data is added with the new function gpiochip_add_data()
and for compatibility we add static inline wrapper function
gpiochip_add() that will call gpiochip_add_data() with
NULL as argument. The latter will be removed once we have
exorcised gpiochip_add() from the kernel.

gpiochip_get_data() is added as a static inline accessor
for drivers to quickly get their data out.

#1368833 — [PATCH 4.2.y-ckt 020/218] clk: rockchip: Add pclk_peri to critical clocks on RK3066/RK3188

4.2.8-ckt7 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Romain Perier <romain.perier@gmail.com>

commit 3bba75a2ec32bd5fa7024a4de3b8cf9ee113a76a upstream.

Now that the rockchip clock subsystem does clock gating with GPIO banks,
these are no longer enabled once during probe and no longer stay enabled
for eternity. When all these clocks are disabled, the parent clock pclk_peri
might be disabled too, as no other child claims it. So, we need to add pclk_peri
to the critical clocks.

4.2.8-ckt7 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Josh Boyer <jwboyer@fedoraproject.org>

commit 4ec0ef3a82125efc36173062a50624550a900ae0 upstream.

The iowarrior driver expects at least one valid endpoint.  If given
malicious descriptors that specify 0 for the number of endpoints,
it will crash in the probe function.  Ensure there is at least
one endpoint on the interface before using it.

The full report of this issue can be found here:

---8<------------------------------------------------------------

From: Alexander Kochetkov <al.kochet@gmail.com>

commit e8b63288b37dbb8457b510c9d96f6006da4653f6 upstream.

hclk_cpubus needs to keep running because it is needed for devices like
the rom, i2s0 or spdif to be accessible via cpu. Without that all
accesses to devices (readl/writel) return wrong data. So add it
to the list of critical clocks.

We need to check if number of gpio is positive if there is no
such check in devicetree or acpi or whatever called before
gpiochip_add.

I suppose that devicetree and acpi do not allow insert gpiochip
with zero number but I do not know if it is enough to ignore
this check in gpiochip_add.

#1368837 — [PATCH 4.2.y-ckt 007/218] gpio: rcar: Add Runtime PM handling for interrupts

4.2.8-ckt7 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Geert Uytterhoeven <geert+renesas@glider.be>

commit b26a719bdba9aa926ceaadecc66e07623d2b8a53 upstream.

The R-Car GPIO driver handles Runtime PM for requested GPIOs only.

When using a GPIO purely as an interrupt source, no Runtime PM handling
is done, and the GPIO module's clock may not be enabled.

To fix this:
  - Add .irq_request_resources() and .irq_release_resources() callbacks
    to handle Runtime PM when an interrupt is requested,
  - Add irq_bus_lock() and sync_unlock() callbacks to handle Runtime PM
    when e.g. disabling/enabling an interrupt, or configuring the
    interrupt type.
